' Application-filed January 13,1902. $e1-ia1No.'89,623. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH LYON, a citizen of the United States,residing at Dayton, Mont gomery county, Ohio, have invented a certain new and useful Look,- of which the following I is a specification, reference being had to the rel by an independent movement 'of the bolt from within. v

My invention consists of the me'ans,'com-% binations, arrangements, and construction of 5' thevarious parts and means, all as hereinlock as viewed fromthe outside. sectional view thereof substantially on line is a sectional view substantially on line X X of Fig. 2. Fig. 4

annexed drawings, forming part hereof, in which drawings like characters of reference indicate the same parts.

My present invention relates to locks, and its embodiment forms what might be termed a combination lock and bolt, and giving the speed and convenience of the ordinary sliding bolt when looking or unlocking from after described, and stated in the claims.

The best means known to me, at this time for accomplishing the objects of my invention in which Figure 1 is an exterior view of aportion of? a door and its casing containing my improved Fig. 2 1s a X X of Fig. 3. Fig. 3

is a view similar to Fig. 1, but as viewed from the opposite or 1n side. Fig. 51s a View on line Y Y of Fig. 2, the security-lock or blind Fig. 6 is a sectional view on line X X of Fig. 5. Fig.2 7 is a central longitudinal sectional view of lock being in its locking position.

the bolt. Figs. 8 and 9 are respectively an.

exterior end-view and a cross-sectional view of said bolt. Fig.- 10 is a view of the outer side of the bolt, showing the horizontal porwall. Fig. 11 is an exterior View of my invention when constructed to insert the lock are illustrated in the accompanying drawings,

tion of its angular slot provided with a topinto the door from ,the outside. Fig. 12 is a sectional view thereof substantially on line X X of Fig. 11, the inner portion of the door and casing being broken away, as that portion of the same is similarto the inner por tion shown in Fig. 2.

The bolt 10 is slidingly mounted 'in the frame consisting of a face-plate 11, to which is rigidly secured a sheet-metal portion 12,

extending at right angles thereto and terminating in a portion 18, bent at right angles to its body, said bolt 10 being slidably mounted in openings in said face-plate 11 and portion 13. From the inner side of said bolt projects a pin or operating member 14 for shooting said bolt from the inside. A slot 15, formed in the door 16 and covered by faceplate 17, secured to the door and similarly slotted, accommodates the projecting'end of pin 14. i In the structures shown in Figs. 1, 2, and 3 the lock ismounted in the usual central mortise-18, which is covered by the face-plate 11 and has extension 19 for the back clearance of the bolt. p 7

The outer face of bolt 10' is provided with a slot 20, consisting of a branch slot extending at right angles to the movement of bolt 10 and, a'separate branchslot extending longitudinally of said bolt 10 and connecting intermediate its ends with one end of said firstnamedbranch slot, which slot 20 is engaged by pin'21, carried by key-barrel 22, mounted in shell 23, which barrel and shell are of the usual Yale construction or otherwise. When said key-barrel isturned by the key, said pin 21,is adapted to drop downward into the vertical branch of said slot 20 in following the arc of the circle described by said pin 21 .in moving with the key-barrel, and by contacting with the walls of said vertical branch of said, slot 20 said pin 21 drives said bolt 10 into or out of its keeper 25 in the door-casing 26,. and which keeper is provided with the iisual face-plate 27. In the positions shown jin Figs. .2 and 3 said key-barrel 22 is in the position where its pin 21 has withdrawn the .;bolt,"1O from its keeper and the door having been opened and closed and th'bldltlO manually shot into its keeper from the inside by pressure on pin 14. The key-barrel 22 is not moved by said manually shooting of bolt 10 and remains in that position to which it was moved by the key in withdrawing bolt 10 from its keeper, but said shooting of bolt 10 moves the vertical branch of slot away from key-barrel pin 21, Figs. 2 and 3, and also brings that portion of the body of bolt 10 represented by one of the horizontal branches of slot 20 across the path of pin 21 to oppose the downward movement of saidv pin 21 in the arc of a circle. The pin on key-barrel casing 23, cooperating with the separated projections 31 on the key-barrel 22, limits the movement of key-barrel 22 to substantially half of a revolution and precludes the possibility of key-barrel 22 shooting bolt 10 by moving with its pin 21 upward, Fig. 3, in the arc of a circle and thence down into the vertical branch of slot 20 and then shooting bolt 10 by further movement of key-barrel 22.

It will thus be seen that it is the shooting of bolt .10 from the inside of the door that locks key-barrel 22 (accessible from the outside of the door) from being turned its normally-allotted half of a revolution even by the proper key by reason of said engagement of key-barrel pin 21 with that part of the horizontal branch of slot 20 on either side of the vertical branch of said slot 20', the pin 21 being normally in the plane of said horizontal branch of slot 20 at each end of the limited half of a revolution of said key-barrel 22, and that when said key-barrel 22 is so locked from movement the lock becomes un pickable from the outside of the door, since said keybarrel 22 is precluded from shooting the bolt 10, and said key-barrel 22 and its shell 23 thereby becomes a deceptive, blind, or dummy lock that cannot be rendered operative even with the appropriate key and that the most skilful burglar would be deceived by this lock, which is most effectively employed as a night-lock when the key-barrel 22 is in such position that if the bolt were controlled thereby at all times instead of only at those times determined by the person within said bolt 10 would be out of its keeper. Consequently the term blind lock or deceptive' lock may be appropriate for this lock, which may or may not be operated from the outside by the appropriate key, according -to the will of the person or persons within in shooting the bolt 10 from the inside or not, and that the construction is such that it is simply the movement of bolt 10 into or out of its keeper when actuated from the inside, which locks the key-barrel from movement even by the proper key.

When the bolt 10 is driven in one direction by pin 21 of key-barrel 22 engaging in the vertical branch of slot 20 in bolt 10 and the bolt is then moved in the opposite direction by pin 14 manually from the inside of the door, the key-barrel thereby becomes locked in the manner before stated.

Pin 30 on shell 23 and projections 31 upon the inner end of the key-barrel 22 may be dispensed with when the slot 20" in the bolt is provided with the horizontal top wall 32, as shown in Fig. 10, the walls of which slot 20" will in this case as eii'ectually limit the revoluble movement of key-barrel 22.

To prevent an entrance being forced by sawing off the bar or bolt 10, l have devised the construction shown in Figs. 7, 3, and 9, in which the bar or bolt 10 is provided with a longitudinal circular opening 33, in which loosely fits a hardened pin 34, prevented lrom escaping from said opening in the instance shown by plug 35, sealing the mouth of said opening 33. Said pin 34 will thus revolve freely in said opening 33 when a saw, lile, or other tool contacts therewith.

The shell 23 of the key-barrel is mounted in plate 12 of the casing by being bodily inserted through opening 40 of plate 12 and through opening 41 in the door 16 until the lip 42 on shell 22) contacts with the outer face of the door, whereupon the lock-easing is pushed completely into its mortise 13, the three faces 43 ot' a lateral extension oi said opening 40 contacting with corresponding angular depressions 44 in the periphery of shell 23, in which position said shell 23 is held by a screw 45, passing through an opening in face-plate 11 and threaded into an opening 46, Figs. 2 and 3, in said shell 23. There are a plurality of said depressions 44 and openings 46 at different points in the length of said keybarrel to accommodate the different thicknesses of doors and other varying conditions.

As a safety night-lock from within for the bolt 10 I suspend plate 50 loosely upon pin 14 by opening 51 for convenience and to prevent said plate being lost. Upon the rear or inner surface of plate 50 is a projection iitting the slot in face-plate 17, with the exception ol a space at one end, which is for the accommodation of pin 14, which projection is formed in the instance shown by securing a plate 52 upon the inner side of plate 50. 'lhrough plates 50 and 52 pass a headed pin 53, adapted l 5 to be revolved by a key fitting into a plurality of recesses 54 in the head thereof. Said recesses 54 are dissimilar to and unsuggestive ol keyholes and the head of pin 53 is intended to convey to the unauthorized the impression 120 that it is but a rigid projection or reliellornament. On the outer end of pin 53 are oppositely-located bolts or looking projections 55 whose lengths are greater than the width ol' the slot in face-plate 17. \Vhen said projec- 5 This inside 2 them.

locking device for the bolt is so minute as to escape observation and is therefore a deceptive or a blind lock, misleading the uninformed into the belief that. the pin 14 is the pin of the ordinary night-lock, which turns upon its axis. The head upon pin 14 is removably secured thereto by threads or otherwise and enables the plate 50 and its attached parts to be removed therefrom at will.

It will thus be seen that the plate 17 constitutes armember against which the projection 14 on bolt 10 is adapted to contact for the purpose of limiting the movement of said bolt 10 and that said projection or plate 52 constitutes a separate member adapted to be placed between said projection 14; and the point where said projection 14s is adapted to contact with said member or plate 17 for further limiting the movement of bolt 10, and that plate 50, pin 53, and projections 55 constitute in the structure shown means for removably securing said projection orplate 52 in said position, and that recesses 54 in said pin 53 constitute in the structure shown deceptive means where by said plate 52 may be released, since said recesses 54 are not suggestive of a keyhole.

In the construction shown in Fig. 12 the same parts that are employed in the previouslydescribed figures are designated with the same reference character, with the addition of the letter B, just as the letter A is employed in, Fig. 10 to distinguish that'modification.

The mortise 18 is cut from the outside face of the door, the lip 42 of shell 23 covering the outer edge of said mortise, the face-plate 11 and the portion 13 being secured to said lip 42 and the bolt 10 being slidably mounted in openings therethrough, the difference inconstruction being that the shell 23 forms the body of the lock-casing and is not independ ent thereof, as is shown in the previous figures of the drawings.

In another application, Serial No. 71,877, filed August 14, 1901, entitled .Burglaralarm house-protector, I have shown and described the lock mechanism herein embodied and have claimed the samein combination with an alarm or burglar-alarm apparatus, and in: asmuch as in that application I could not claim the structures of this apparatus independent of or unrelated to said alarm apparatus this application is for the purpose of so claiming Inasmuch as I could not claim in this application the construction of the bolt 10, containing the pin 34c in structural and functional relations and combinations other than substantially those herein shown and described, therefore I have in another application, entitled J ail or burglar-proof construction, filed June 5, 1903, serially numbered 160,150, shown and claimed. such str'ucture in structural and functional relations and combinations forming the bars of a jail or analogous barred structure.
